Bias voltage and temperature dependence of hot electron magnetotransport

Bias Voltage and Temperature Dependence of Hot Electron Magnetotransport

We present a qualitative model study of energy and temperature dependence of hot electron magnetotransport. This model calculations are based on a simple argument that the inelastic scattering strength of hot electrons is strongly spin and energy dependent in the ferromagnets. Since there is no clear experimental data to compare with this model calculations, we are not able to extract clear phy...

Dissimilar Ferromagnetic Layer Dependence of Hot Electron Magnetotransport

The material dependence of hot electron magnetotransport in a spin-valve transistor has been theoretically explored. We calculate the parallel and antiparallel collector current changing the types and relative spin orientation of the ferromagnetic layers. The magnetocurrent has been presented as well. In this calculations, spin dependent self energy effect of hot electron in ferromagnetic mater...

Critical Temperature Dependence of High Frequency Electron Dynamics in Superconducting Hot-Electron Bolometer Mixers

Critical Temperature Dependence of High Frequency Electron Dynamics in Superconducting Hot-Electron Bolometer Mixers Irfan Siddiqi May, 2002 Superconducting diffusion-cooled hot-electron bolometer (HEB) mixers are ideal candidates for use in terahertz heterodyne spectroscopy (THz). This thesis investigates mixer performance as a function of the superconducting transition temperature (Tc). In th...
